The present invention relates to epothilon derivatives, processes for their production and their use in the manufacture of medicaments and plant protection agents. The prosthesis has a trunk divided by an internal septum, which defines, within at least a portion of the trunk interior, a multi-lumen flow channel configuration. The main switch array receives the digital data and outputs a voltage if the digital data is in a first range. Variance induced by the noise may differentiate the sample from one or more of the exemplars. For example, the agent may respond with an exclusive ownership indication. The terminus orifice and exit plane of the baffle preferably projects and terminates within the interior fluid passageway beyond the surface thereof so that liquids pooled within the passageway can be retained therein without draining into the medication port.
